Approach:
Two mutually supporting approaches will be taken to meet our objectives. The first involves a series of field studies to identify new (e.g. cuphea, pennycress, and bifora) and alternative crop genotypes (e.g. camelina and calendula), develop practices to manage them, and use these crops along with traditional crops to develop alternative strategies (double- and relay-cropping) to add innovative economic and environmental benefits. Additionally, controlled-environment and field experiments will be conducted to determine environmental limitations (e.g. water and soil and air temperature) to growth of new and alternative crops. The second approach involves the integration of field and controlled-environment experiments of weed growth and development, innovative weed control methods, and computer modeling to develop decision support aids to efficiently and effectively manage weeds in cropping systems that include new and alternative, as well as traditional crops. Together the outcomes of this research will provide clientele with new knowledge, crops, and management tools to increase cropping efficiency and diversity in northern climates.
